Web Inspector: debugger should be able to show variable types
https://bugs.webkit.org/show_bug.cgi?id=133395
Reviewed by NOBODY (OOPS!).
Increase the amount of type information the VM gathers when directed
to do so. This initial commit is working towards the goal of
capturing, and then showing (via the Web Inspector) type information for all
assignment and load operations. This patch doesn't have the feature fully
implemented, but it ensures the VM has no performance regressions
unless the feature is specifically turned on.
